Abstract Application of polyester‐degrading microorganisms or enzymes should be considered as an eco‐friendly alternative to chemical recycling due to the huge plastic waste disposal nowadays. However, current impranil DLN‐based screening of polyester‐degrading microorganisms is time‐consuming, labour‐intensive and unable to distinguish polyesterases from other protease‐ or amidase‐like enzymes. Herein, we present an approach that combined a novel synthetic fluorescent polyurethane analogue probe (FPAP), along with the droplet‐based microfluidics to screen polyurethane‐degrading microorganisms through fluorescence‐activated droplet sorting (FADS) pipeline. The fluorescent probe FPAP exhibited a fluorescence enhancement effect once hydrolysed by polyesterases, along with a strong specificity in discriminating polyesterases from other non‐active enzymes. Application of FPAP in a microfluidic droplet system demonstrated that this probe exhibited high sensitivity and efficiency in selecting positive droplets containing leaf‐branch compost cutinase (LCC) enzymes. This novel fluorogenic probe, FPAP, combined with the droplet microfluidic system has the potential to be used in the exploitation of novel PUR‐biocatalysts for biotechnological and environmental applications. |
